Description

Description Stirring deaerator and container used therefor

TECHNICAL FIELD The present invention relates to an agitation deaerator and a container used therefor, and in particular, an agitation deaerator that stirs an object to be processed while discharging (degassing) air bubbles in the object to be processed outside and the object to be processed Related to the container to be used. Background art

As a conventional stirring deaerator, the container holder that holds the container for storing the workpiece is revolved, and the container holder is rotated on its orbit, thereby stirring the workpiece while degassing (stirring). There is known an agitation / defoaming apparatus that mixes, disperses or kneads the mixture (for example, see Japanese Patent Application Laid-Open No. 10-435568). In this stirring and defoaming device, a container holder is rotatably attached to a peripheral portion of a rotating body, and the container holder is rotated on the rotating body while rotating the rotating body and revolving the container holder. ing. In such a stirring and defoaming device, the object to be treated in the container is pressed against the inner wall surface of the container by the centrifugal force acting by the revolution of the container holder, and the bubbles in the object to be treated are released (defoamed) to the outside. The In addition, the rotation of the container holder causes a difference in the moving speed of molecules of the object to be processed (shearing speed) near and away from the inner wall surface of the container. This shearing speed generates shearing force and generates heat. However, the flow state of the workpiece is continuously maintained, and the entire workpiece is stirred. Note that the higher the revolution speed of the container holder, the better the defoaming action, and the higher the rotation speed, the better the stirring action.

In particular, in the conventional stirring and degassing apparatus described above, the container holder that holds the substantially cylindrical container is supported so as to be rotatable about an axis inclined with respect to the revolution axis of the rotating body. When rotating while revolving, the object to be processed in the container can flow in the vertical direction along the inner wall surface of the container, and the object to be processed can be stirred while sufficiently degassing. However, if the rotation axis of the container holder is inclined with respect to the revolution axis of the rotating body as in the conventional stirring and degassing apparatus described above, the rotation radius of the rotating body becomes large and the entire apparatus becomes large. In addition, the power transmission mechanism for rotating the container holder is complicated.

On the other hand, in order to reduce the size of the conventional stirring and defoaming apparatus described above and to make the power transmission mechanism simple, the container holder has a rotation axis substantially parallel to the revolution axis of the rotating body. It is not possible to stir while sufficiently defoaming the material to be processed by causing the material to be processed to flow vertically along the inner wall surface of the container, especially when there is a small amount of material to be processed. It cannot be stirred while defoaming. Disclosure of the invention

Hereinafter, embodiments of a stirring and defoaming device according to the present invention and a container used therefor will be described in detail with reference to the accompanying drawings.

[First embodiment]

FIG.1A to FIG.2 show a first embodiment of the stirring and deaerator according to the present invention. The stirring and defoaming device of this embodiment is a device that stirs an object to be processed while releasing bubbles in the object to be processed (defoaming). As the object to be processed, a paste-like (strongly viscous) Liquid materials) and powder materials, such as solder paste, dental impression materials, oils and fats, resins, pigments, various powders, and composite materials such as power composites used in aircraft and vehicle bodies (Epoxy resin, phenol resin, etc.) can be processed.

As shown in FIG. 1A, the stirring and defoaming device 10 of the present embodiment includes a rotation drive mechanism 1 2 and a rotating body 14 4 that can be rotated (revolved) by the rotation drive mechanism 1 2. A container holder 16 that can be rotated (rotated) on the rotating body 14, a power transmission mechanism 1 8 that rotates (rotates) the container holder 16 by rotation (revolution) of the rotating body 14, And a counterweight 46 mounted on the rotating body 14, and these are accommodated in a housing (not shown).

The rotation drive mechanism 12 is fixed in the housing via a support (not shown), and a motor 20 and a virtual straight line (revolution axis) fixed to the rotation axis of the motor 20 and extending in a substantially vertical direction. ) Revolving shaft 2 2 that rotates around L 1.

The rotating body 14 is composed of a flat plate-like member extending in the left-right direction in FIG. 1 A, and the substantially central portion of the bottom surface is attached to the revolution shaft 2 2 of the rotation drive mechanism 1 2, and the rotation drive mechanism 1 2 The revolution axis 2 2 rotates (revolves) in a substantially horizontal direction around the revolution axis L 1.

The container holder 16 is fixed to the rotating shaft 24 at the substantially central portion of the bottom surface thereof, and the rotating shaft 24 is attached to the periphery of the rotating body 14 via the bearing 26 so that it can rotate (spin). It is Accordingly, the container holder 16 is rotated by the revolution shaft 2 2 of the rotation drive mechanism 1 2. While rotating (revolving) around the revolution axis L 1 together with the rotating body 14 by rotation, the power transmission mechanism 18 is separated from the revolution axis L 1 and extends substantially parallel to the revolution axis L 1 by the power transmission mechanism 18 Straight line (spinning axis) L 2 rotates (spins) in a substantially horizontal direction around the center. By making the rotation axis L 2 substantially parallel to the revolution axis L 1 in this way, the rotation axis L 2 is not substantially parallel to the revolution axis L 1 but compared to the case where it intersects the revolution axis L 1 at a predetermined angle. Thus, the rotation (revolution) radius of the rotating body 14 can be reduced to reduce the size of the stirring deaerator 10.

The container holder 16 has a substantially cylindrical outer shape, and a container holding part 30 for holding the container 28 (see FIG. 1B) is formed therein. The container holding portion 30 is defined by a substantially circular bottom surface 3 2 and a side surface 3 4, has an opening at the top, and has a shape that is substantially rotationally symmetric with respect to the rotation axis L 2 passing through the center of the bottom surface 3 2. Have. The upper side surface 36 of the upper side of the substantially vertical central portion of the side surface 3 4 of the container holding portion 30 has a substantially truncated cone shape (a shape obtained by cutting the top of the conical shape substantially parallel to the bottom surface). The lower side surface 38 on the lower side of the substantially vertical central portion of the side surface 34 of the part 30 has a shape obtained by vertically inverting the substantially truncated cone shape.

That is, the inner diameter of the container holding portion 30 becomes maximum at the substantially vertical central portion, and gradually decreases from the substantially vertical central portion toward the bottom surface 32 and the upper opening, and the bottom surface 32 and Minimized at top opening. Further, in the cross section along the rotation axis L 2 of the container holding portion 30, the upper side surface 3 6 and the lower side surface 3 8 of the side surface 3 4 of the container holding portion 30 extend substantially linearly, and the upper side surface 3 Between the 6 and the lower side surface 3 8, there is a cornered portion.

Accordingly, the upper side surface 3 6 and the lower side surface 3 8 of the side surface 3 4 of the container holding part 30 are respectively directed upward and downward from a virtual plane substantially perpendicular to the rotation axis L 2. Therefore, it extends so as to approach the rotation axis L 2 and extends substantially linearly in the cross section along the rotation axis L 2 of the container holding part 30.

The power transmission mechanism 18 is a first pulley which is arranged coaxially with the rotation shaft of the motor 20 of the rotation drive mechanism 12 and is rotatable with respect to the rotation body 14 and fixed to a support body (not shown). 4 0, a rotating shaft 2 fixed to the bottom surface of the container holder 1 6, a second pulley 4 2 fixed to the 4 4, and a bridge between the first pulley 4 0 and the second pulley 4 2. And has the same function as the planetary gear mechanism. For example, when the rotating body 1 4 rotates counterclockwise around the revolution axis L 1 (revolution), the container holder 16 fixed to the second pulley 4 2 rotates counterclockwise around the revolution axis L 1. It rotates (revolves) clockwise around the rotation axis L 2 at the desired number of rotations. The radius ratio between the first pulley 40 and the second pulley 42 can be appropriately changed according to the rotational speed of the motor 20 and the desired rotational speed of the container holder 16. By making the rotation axis L 2 substantially parallel to the revolution axis L 1, the torque transmission mouth of the power transmission mechanism 18 can be made extremely small and the stirring deaerator 10 can be operated efficiently. Can do.

The counterweight 4 6 is attached to the opposite side of the container holder 16 with respect to the revolution axis L 1 on the rotary body 14 so as to balance with the container holder 16 attached near the periphery of the rotary body 14. It has been. By attaching the counterweight 4 6 in this way, the rotating body 14 can smoothly rotate (revolve) in the substantially horizontal direction around the revolution axis L 1 by the rotation of the revolution shaft 2 2 of the rotation drive mechanism 1 2. Can do.

As shown in FIG. 2, the container 28 has a substantially circular bottom surface portion 2 8 a having an outer diameter substantially equal to the diameter of the bottom surface 32 of the container holding portion 30 of the container holder 16, and a substantially cylindrical shape. It consists of side parts 2 8 b. The container 28 is integrally formed of a flexible material such as silicone rubber or fluorine rubber, and accommodates the workpiece M and is mounted in the container holder 16 as shown in FIG. 1B. After that, when rotating around the rotation axis L 2, the side surface portion 28 b can be deformed into a shape along the side surface 34 of the container holding portion 30 of the container holder 16.

Next, the operation of the stirring and deaerator 10 configured as described above will be described. First, the workpiece M is placed in the container 28 and mounted in the container holder 16, and then the rotating body 14 is rotated in the substantially horizontal direction around the revolution axis L 1 by the rotation drive mechanism 12 (revolution). Then, the power transmission mechanism 18 rotates the container holder 16 about the rotation axis L 2 in a substantially horizontal direction (rotation). While the container holder 16 is rotating while revolving in this way, the container 28 is deformed into a shape along the side surface 34 of the container holder 30 of the container holder 16 and revolves together with the container holder 16. Rotating while the workpiece M in the container 28 is farthest from the revolution axis L 1 of the inner wall surface of the container 28 (maximum centrifugal force action region) To be collected. That is, the workpiece M in the container 28 moves along the inner wall surface of the side surface portion 28b of the container 28, and the maximum diameter portion of the side surface portion 28b of the container 28 (of the container holder 16). The container holding portion 30 is gathered in a region farthest from the revolution axis L 1 of the inner wall surface of the side surface 3 4 of the container 3, which faces the boundary region between the upper side surface 3 6 and the lower side surface 3 8. In this way, the workpiece M in the container 28 is pressed against the inner wall surface of the container 28 by the centrifugal force acting by the revolution of the container 28, and the bubbles in the workpiece M are released to the outside. (Defoaming), and the rolling of container 28 causes a difference in the movement speed (shearing speed) of the molecules of object M between the vicinity of the inner wall of container 28 and the place away from it. While shearing force is generated by the shear rate and heat is generated, the flow state of the workpiece is continuously maintained, and the entire workpiece is stirred.

Thus, in the stirring and defoaming apparatus 10 according to the present embodiment, the workpiece M in the container 28 moves along the inner wall surface of the side surface portion 28b of the container 28. The workpiece M can be stirred and defoamed with high accuracy.

In particular, in the stirring and defoaming device 10 of the present embodiment, the upper side surface 3 6 and the lower side surface of the side surface 3 4 of the container holding portion 30 in the cross section along the rotation axis L 2 of the container holding portion 30. 3 8 extends substantially linearly, and a square portion is formed in the boundary region between the upper side surface 3 6 and the lower side surface 3 8, so that the amount of workpiece M is very small (for example, about I mg). Even in such a case, it is possible to collect in a very narrow area in the container 28 and to stir and degas the workpiece M accurately and reliably. In addition, since the workpiece M can be collected in a very narrow area in the container 28, the workpiece M can be easily recovered from the container 28.

Further, in the stirring and defoaming apparatus 10 of the present embodiment, since the revolution axis L 1 and the rotation axis L 2 are substantially parallel, the revolution axis L 1 and the rotation axis L 2 are not substantially parallel but at a predetermined angle. Compared to the case where the rotors intersect with each other, the rotation (revolution) of the rotating body 14 can be reduced to reduce the size of the stirring deaerator 10 and reduce the torque transmission loss of the power transmission mechanism 18. The stirring deaerator 10 can be operated efficiently by making it extremely small.

(First variation)

FIG. 3 shows a first modification of the stirring and defoaming device 10 of the first embodiment. Yes. In this modification, instead of the flat plate-like rotating body 14, the upper opening of the container holder 30 of the container holder 1 6 is inclined toward the revolution axis L 1 and the rotation axis L 2 becomes the revolution axis L 1. A rotating body 1 14 is provided in which a portion to which the container holder 16 is attached is inclined and bent with respect to the other portion so as to intersect at a predetermined angle, for example, 45 °. Other configurations are the same as those in the first embodiment described above, and thus the description thereof is omitted.

It has a shape that becomes The upper side surface 2 3 6 on the upper side of the substantially vertical center of the side surface 2 3 4 of the container holding portion 2 3 0 has a substantially truncated cone shape (a shape obtained by cutting the top of the cone shape substantially parallel to the bottom surface), The lower side surface 2 3 8 on the lower side of the substantially vertical central portion of the side surface 2 3 4 of the container holding portion 2 30 has a shape obtained by vertically inverting the substantially truncated cone shape. That is, the inner diameter of the container holding portion 2 30 is maximized at the substantially vertical central portion, and from the substantially vertical central portion to the bottom surface 2. 3 Decreasing toward the 2 and top openings, minimizing at the bottom 2 3 2 and top openings. Further, in the cross section along the rotation axis L 2 of the container holding portion 2 3 0, the upper side surface 2 3 6 and the lower side surface 2 3 8 of the side surface 2 3 4 of the container holding portion 2 3 0 extend substantially linearly. Thus, a cornered portion is formed between the upper side surface 2 3 6 and the lower side surface 2 3 8.

In addition, the corner protruding between the upper side surface 2 3 6 and the lower side surface 2 3 8 of the side surface 2 3 4 of the container holding portion 2 3 0 has a corner protruding radially inward of the container holding portion 2 3 0. A protrusion portion 25 4 having a rectangular cross section having a portion is formed so as to extend in the circumferential direction over the entire periphery of the side surface 2 34 of the container holding portion 2 30.

Further, by forming a notch 2 2 8 c in the outer periphery of the side surface 2 2 8 of the container 2 2 8, the side surface 2 3 of the container holding portion 2 3 0 4 Even if the angle between the upper side surface 2 3 6 and the lower side surface 2 3 8 is reduced, the side surface portion 2 2 8 b of the container 2 2 8 is aligned with the side surface 2 3 4 of the container holding portion 2 3 0 Since it can be easily deformed into a shape, the workpiece M can be collected in an extremely narrow area in the container 28 and accurately and reliably stirred and degassed. Further, the side surface 2 2 8 b of the container 2 2 8 is formed on the outer periphery of the ID 2 2 8 ID by forming a cut 2 2 8 c. The container 2 2 8 can be prevented from being damaged when deformed into a shape conforming to 4.

In this modified example, since the stopper portion 2 5 6 is formed at the upper end of the upper side surface ² 3 6 of the side surface 2 3 4 of the container holding portion 2 3 0, the container 2 2 8 becomes the container holder 2 1 6 Rotate while revolving and agitate and degas the workpiece, and even if the container holder 2 1 6 stops, the upper end surface of the container 2 2 8 abuts against the stopper portion 2 5 6 and the container 2 2 8 can maintain the deformed state. Therefore, it is possible to prevent the shape of the container 2 28 from changing suddenly, and to prevent the object to be processed from diffusing in the container 2 28.

(Third modification)

F IG .6 A and F IG .6 B are enlarged views of a modified portion of the third modified example of the stirring and degassing apparatus 10 according to the first embodiment.

Silicone rubber or fluororubber Etc., which are integrally formed of a flexible material. The outer diameter of the side surface 3 2 8 b of the container 3 2 8 is the smallest at the substantially vertical central part, and gradually increases from the substantially vertical central part toward the lower end of the upper end and at the upper and lower ends. It is the largest and is approximately equal to the inner diameter of the container holder 3 1 6. Therefore, the thickness of the side surface portion 3 2 8 b of the container 3 2 8 is minimized at the substantially vertical center portion, and gradually increases from the substantially vertical center portion toward the upper end and the lower end, Maximum at the bottom.

Container 3 2 8 is installed in container holder 3 1 6 as shown in FIG. After rotating around the rotation axis L 2, the outer wall surface of the side surface portion 3 2 8 b is deformed so as to be substantially cylindrical and pressed against the inner wall surface of the substantially cylindrical housing portion of the container holder 3 1 6. It comes to adhere. Further, due to the deformation of the container 3 2 8, the upper inner wall surface 3 2 8 d on the upper side of the substantially vertical center portion of the side surface of the container 3 2 8 has a substantially truncated cone shape (the top of the cone is substantially parallel to the bottom surface). The lower inner wall surface 3 2 8 e of the lower side of the substantially vertical center portion of the side surface of the container 3 2 8 has a shape obtained by vertically inverting the substantially truncated cone shape. That is, the inner diameter of the container 3 2 8 becomes maximum at the substantially vertical central portion, and gradually decreases from the substantially vertical central portion toward the bottom surface 3 2 8 f and the upper opening, and the bottom surface 3 2 8 Minimized at top opening. Further, in the cross section along the rotation axis L 2 of the container 3 2 8, the upper inner wall surface 3 2 8 d and the lower inner wall surface 3 2 8 e of the side surface of the container 3 2 8 extend substantially linearly, A cornered portion is formed between the wall surface 3 2 8 d and the lower inner wall surface 3 2 8 e.

In this modified example as well, the object to be processed can be agitated and defoamed with high accuracy in the same manner as the agitating and defoaming apparatus 10 of the first embodiment described above.

(Fourth modification)

F IG .7 A and F IG .7 B are enlarged views of a modified portion of the fourth modification of the stirring and deaerator 10 of the first embodiment. In this modification, a container holder 4 16 is used instead of the container holder 16. This container holder 4 1 6 has a diameter of the container holding part 4 3 0 in a corner portion between the upper side face 4 3 6 and the lower side face 4 3 8 of the side face 4 3 4 of the container holding part 4 3 0. The four protrusions 4 5 4 on the curved surface protruding inward in the direction are formed as described above except that they are formed at predetermined intervals in the circumferential direction of the side surface 4 3 4 of the container holding part 4 3 0. This is substantially the same as the container holder 16 of the first embodiment. Other configurations are substantially the same as those of the first embodiment described above, and thus the description thereof is omitted.

(Fifth modification)

FIG. 8A and FIG. 8B show an enlarged view of the deformed portion of the fifth modification of the stirring and defoaming device 10 of the first embodiment. In this variant, the container holder 1 Instead of 6, a substantially cylindrical container holder 5 1 6 having a substantially circular bottom is used, and a container 5 2 8 is used instead of the container 2 8. Other configurations are the same as those of the above-described first embodiment, and thus description thereof is omitted.

The container 5 28 has a substantially circular opening at the top, and is composed of a substantially circular bottom surface portion 5 2 8 a and a side surface portion 5 2 8 b having a substantially cylindrical outer wall surface. The outer diameter of the side surface portion 5 2 8 b of the container 5 28 is substantially the same as the inner diameter of the container holder 5 16, and is fitted and held in the container holder 5 16. The upper inner wall surface 5 2 8 d on the upper side of the substantially vertical center portion of the side surface of the container 5 2 8 has a substantially truncated cone shape (a shape obtained by cutting the top of the cone shape substantially parallel to the bottom surface). The lower inner wall surface 5 2 8 e on the lower side of the center portion in the substantially straight direction of the side surface of 8 has a shape obtained by vertically inverting the substantially truncated cone shape. That is, the inner diameter of the container 5 2 8 becomes maximum at the substantially vertical central portion, and gradually decreases from the substantially vertical central portion toward the bottom surface 5 2 8 f and the upper opening, and the bottom surface 5 2 8 f and Minimized at top opening. In addition, in the cross section along the rotation axis L 2 of the container 5 28, the upper inner wall surface 5 2 8 d and the lower inner wall surface 5 2 8 e on the side surface of the container 5 28 extend substantially linearly, A cornered portion is formed between the inner wall surface 5 2 8 d and the lower inner wall surface 5 2 8 e. In this modification, the container 5 28 does not need to be deformed, so it is not necessarily formed of a flexible material such as silicone rubber or fluorine rubber.

Also in this modified example, similarly to the stirring deaerator 10 of the first embodiment described above, the workpiece M can be accurately stirred and defoamed.

(Other variations)

In the first embodiment described above, when the container holder 16 is rotated (revolved) in the substantially horizontal direction around the revolution axis L 1 by the rotation drive mechanism 12, the container holder 1 6 is driven by the power transmission mechanism 18. Rotates around the rotation axis L 2 in a substantially horizontal direction (rotation). However, the container holder 16 may not rotate even if the container holder 16 is revolved, or the container holder 1 The angular speed of rotation of the container holder 16 may be extremely small (for example, about 1/40) with respect to the angular speed of rotation of 6, or the container holder 16 may be independently rotated and rotated at a desired angular speed. In this way, after stirring and defoaming the workpiece, the container holder 16 In a state where the container holder 16 is rotated at a very low angular velocity, the object M in the container 2 8 is moved between the upper side surface 3 6 and the lower side surface 3 8 by revolving the container holder 16. Collecting in a narrower boundary area (extremely narrow area farthest from the revolution axis L 1), the workpiece M can be defoamed more accurately and reliably, and after the defoaming, The processed material M can be recovered from the container 28 more easily.

[Second Embodiment]

F IG .9 to F IG .12 D show a second embodiment of the stirring and deaerator according to the present invention. As in the first embodiment, the stirring and defoaming device of the present embodiment is a device that stirs the workpiece while releasing (defoaming) bubbles in the workpiece to the outside. As paste (highly viscous liquid) and powder materials, such as solder paste, dental impression materials, oils and fats, resins, facials, various powders, as well as aircraft and vehicle bodies It is possible to process materials such as composite materials such as epoxy resin and phenolic resin.

As shown in FIG. 9, the stirring and degassing device 6 1 0 of the present embodiment includes a rotation drive mechanism 6 1 2 and a rotating body 6 1 4 that can be rotated (revolved) by the rotation drive mechanism 6 1 2. And a pair of substantially cylindrical container holders 6 1 6 having a substantially circular bottom surface attached to the rotating body 6 14 to be able to rotate (spin), and rotation (revolution) of the rotating body 6 14 And a power transmission mechanism 6 18 that rotates (spins) the pair of container holders 6 1 6, and these are accommodated in a housing (not shown).

The rotation drive mechanism 6 1 2 is fixed in the housing via a support (not shown), and a motor 6 2 0 and a virtual straight line (fixed to the rotation shaft of the motor 6 2 0 and extending in a substantially vertical direction) Revolving axis) Revolving shaft 6 2 2 rotating around L 1 is provided.

The rotating body 6 14 is made of a flat plate-like member extending in the left-right direction in FIG. 9, and the substantially central portion of the bottom surface is attached to the revolution shaft 6 2 2 of the rotation driving mechanism 6 1 2, so that the rotation driving mechanism 6 1 2 Revolving shaft 6 2 2 rotates (revolves) in a substantially horizontal direction around the revolution axis L 1.

The pair of container holders 6 16 are arranged in the vicinity of the peripheral edge portions on the opposite side with respect to the revolution axis L 1 on the rotating body 6 14. Each container holder 6 1 6 is an abbreviation of its bottom surface. The center part is fixed to the rotating shaft 6 2 4, and the rotating shaft 6 2 4 is attached to the periphery of the rotating body 6 14 via the bearing 6 2 6 so as to be rotatable (spinning). Accordingly, each container holder 6 1 6 rotates (revolves) in the substantially horizontal direction around the revolution axis L 1 together with the rotating body 6 1 4 by the rotation of the revolution shaft 6 2 2 of the rotation drive mechanism 6 1 2. The power transmission mechanism 6 1 8 rotates (rotates) in a substantially horizontal direction around a virtual straight line (spinning axis) L 2 that is separated from the revolving axis L 1 and extends substantially parallel to the revolving axis L 1. Yes. When the rotation axis L 2 is made substantially parallel to the revolution axis L 1 in this way, the rotation axis L 2 is not substantially parallel to the revolution axis L 1 but intersects the revolution axis L 1 at a predetermined angle. Compared to the above, the rotation (revolution) radius of the rotating body 6 14 can be reduced, and the stirring and deaerator 6 10 can be downsized.

The power transmission mechanism 6 1 8 is arranged coaxially with the rotation shaft of the motor 6 2 0 of the rotation drive mechanism 6 1 2, can rotate with respect to the rotation body 6 1 4, and is fixed to a support body (not shown). + The first pulley 6 4 0, the second pulley 6 4 2 fixed to the rotation shaft 24 4 fixed to the bottom surface of each container holder 6 1 6 and the first pulley 6 4 0 The belt 6 4 4 is provided between the second pulleys 6 4 2 and 6, and has the same function as the planetary gear mechanism. For example, when the rotating body 6 1 4 rotates (revolves) counterclockwise around the revolution axis L 1, the container holders 6 1 6 fixed to the respective second pulleys 6 4 2 have the revolution axis L It rotates (revolves) counterclockwise around 1 and rotates (rotates) clockwise around the rotation axis L 2 at the desired number of rotations. The radius ratio between the first pulley 6 40 and the second pulley 6 4 2 can be appropriately changed according to the rotational speed of the motor 6 20 and the desired rotational speed of the container holder 6 16. By making the rotation axis L 2 substantially parallel to the revolution axis L 1, the torque transmission loss of the power transmission mechanism 6 1 8 can be made extremely small, and the stirring deaerator 6 10 can be operated efficiently. Can do.

As shown in F IG .10 A and F IG.10 B, the containers 6 2 8 held in the respective container holders 6 16 are composed of a container body 6 5 8 and a lid body 6 60.

The container main body 6 58 has a substantially circular opening at the top, and is composed of a substantially circular bottom surface portion 6 5 8 a and a side surface portion 6 5 8 b having a substantially cylindrical outer wall surface. The container body 6 5 8 has a side surface 6 5 8 b whose outer diameter is substantially the same as the inner diameter of the container holder 6 1 6. It is designed to be fitted and held within 1-6. The thickness of the side surface 6 5 8 b of the container body 6 5 8 is the center line extending in the vertical direction through the center of the bottom surface 6 5 8 a of the container body 6 5 8 (line corresponding to the rotation axis L 2) From the portion on the virtual plane 6 5 8 c that passes through the approximate center of the line in the container body 6 5 8 and is inclined at a predetermined angle with respect to the bottom surface 6 5 8 a of the container body 6 5 8 , Gradually increasing towards the bottom surface 6 5 8 f and the top opening, maximizing at the bottom surface 6 5 8 f and the top opening. In addition, in the cross section along the rotation axis L 2 of the container body 6 5 8, the upper inner wall surface 6 5 8 d on the upper side of the container body 6 5 8 in the substantially vertical direction and the lower inner wall surface 6 on the lower side in the substantially vertical direction 6 5 8 e extends substantially linearly, and an angular portion is formed in the boundary region between the upper inner wall surface 6 5 8 d and the lower inner wall surface 6 5 8 e.

Accordingly, the upper inner wall surface 6 5 8 d and the lower inner wall surface 6 5 8 e on the side surface of the container body 6 5 8 are respectively set to a predetermined angle from the rotation axis L 2, preferably an angle of 45 degrees or less, and Preferably, as it goes upward and downward from a virtual plane inclined by an angle of 30 degrees or less, it extends so as to approach a line corresponding to the rotation axis L 2, and along the rotation axis L 2 of the container body 6 5 8. In the cross section, each extends substantially linearly.

The lid body 6 60 is fitted into the inner lid 6 60 a which fits in the upper opening of the container body 6 5 8 and closes the opening, and is fitted into the outer peripheral surface of the upper part of the container body 6 5 8. And an outer lid 6 60 b that prevents the lid 6 60 a from falling off, so that the inner space of the container body 6 58 can be hermetically sealed.

Next, the operation of the stirring deaerator 6 10 will be described with reference to F IG .11 to F IG .12 D.

First, the workpiece M is put in each container 6 2 8 and mounted in the container holder 6 1 6, and then the rotating body 6 1 4 is moved about the revolution axis L 1 by the rotation drive mechanism 6 1 2. When rotated (revolved) in the horizontal direction, each container holder 6 1 6 is rotated (rotated) about the rotation axis L 2 by the power transmission mechanism 6 1 8. In this way, while each container holder 6 1 6 rotates while revolving, the workpiece M in each container 6 2 8 is farthest from the revolution axis L 1 of the inner wall surface of the container 6 2 8. Collected in the area (maximum centrifugal force action area). That is, the workpiece M in each container 6 2 8 is a container 6 2 8 Moves along the inner wall surface of the side surface of the container 6 2 8 and is farthest from the revolution axis L 1 of the boundary region between the upper inner wall surface 6 5 8 d of the side surface of the container 6 2 8 and the lower inner wall surface 6 5 8 e Gathered in a certain area.

In this way, the workpiece M in the container 6 2 8 is pressed against the inner wall surface of the container 6 2 8 by the centrifugal force acting by the revolution of the container 6 2 8, and the bubbles in the workpiece M are removed. The difference in the movement speed of the molecules of the workpiece M between the vicinity of the inner wall surface of the container 6 2 8 and the place away from it (shearing speed) due to the rotation of the container 6 2 8 As the shear rate is generated due to this shearing speed and heat is generated, the flow state of the workpiece is continuously maintained, and the entire workpiece is stirred.

Thus, in the stirring deaerator 6 10 of the present embodiment, the workpiece M in the container 6 2 8 moves along the inner wall surface of the side surface of the container 6 2 8. The workpiece M can be stirred and defoamed with high accuracy.

In particular, in the stirring and defoaming device 6 10 of the present embodiment, the virtual plane 6 connecting the boundary region between the upper inner wall surface 6 5 8 d of the side surface of the container body 6 5 8 and the lower inner wall surface 6 5 8 e 6 5 8 c is inclined at a predetermined angle with respect to the bottom surface 6 5 8 a of the container body 6 5 8, so that the height of the maximum centrifugal force acting area is increased while the container holder 6 1 6 is rotating. Changes. Therefore, even if the revolution axis L 1 and the rotation axis L 2 are substantially parallel, while the container holder 6 1 6 is rotating while rotating, the workpiece M is placed at the height of the container body 6 5 8. It can flow in the direction (up and down). That is, while the container holder 6 1 6 revolves while rotating, the workpiece M is collected in the lowest maximum centrifugal force acting region as shown in FIG. As shown in FIG. 1 2 B, it is collected in the higher maximum centrifugal force action region, and then as shown in FIG. 1 2 C, it is collected in the highest maximum centrifugal force action region, and then FIG. As shown in 2D, it is collected in the lower area of maximum centrifugal force action. By repeating such a flow, the workpiece M convects while receiving centrifugal force, so that the workpiece M can be stirred and defoamed with high accuracy.

Thus, in the agitation deaerator 6 10 of the present embodiment, the object M in the container 6 28 is contained in the container 6 28 even if the revolution axis L 1 and the rotation axis L 2 are substantially parallel. 6 2 8 It can flow in the height direction (vertical direction), so the workpiece can be processed with a very simple structure. M can be stirred and defoamed with high accuracy.

Further, in the stirring and defoaming device 6 10 of the present embodiment, the upper inner wall surface 6 5 8 d and the lower side of the side surface of the container body 6 5 8 in the cross section along the rotation axis L 2 of the container body 6 5 8 The inner wall surface 6 5 8 e extends substantially linearly, and an angular portion is formed in the boundary region between the upper inner wall surface 6 5 8 d and the lower inner wall surface 6 5 8 e. Even when the amount of M is very small (for example, about I mg), it can be collected in an extremely narrow area in the container 6 28 and the object to be processed M can be stirred and defoamed accurately and reliably. In addition, the workpiece M

Since it can be collected in a very narrow area in 6 2 8, the workpiece M can be easily recovered from the container 6 2 8.

Further, in the stirring and degassing apparatus 6 10 of the present embodiment, since the revolution axis L 1 and the rotation axis L 2 are substantially parallel, the revolution axis L 1 and the rotation axis L 2 are not substantially parallel but have a predetermined value. The rotation (revolution) of the rotating body 6 1 4 can be made smaller by reducing the radius of the rotating body 6 1 4 compared to the case where they intersect at an angle, and the torque transmission of the power transmission mechanism 6 1 8 can be reduced. It is possible to operate the stirring and defoaming device 6 10 efficiently with extremely small loss.

(First variation)

F IG .1 3 A and F IG .1 3 B are enlarged views of the deformed portion of the first modified example of the stirring and deaerator 6 10 of the second embodiment. In this modification, the container body 7 5 8 is used instead of the container body 6 5 8. Other configurations are substantially the same as those of the above-described second embodiment, and thus description thereof is omitted.

In the container main body 7 5 8 of this modification, instead of the virtual plane 6 5 8 c of the container main body 6 5 8, a pair of virtual plane portions 7 5 8 c (each container main body separated by a predetermined distance in the height direction). 7 5 8 bottom surface portion 7 5 8 a center line container body extending vertically through the center of a

7 5 8 A pair of imaginary plane portions 7 5 8 c) passing through substantially the center of a line segment and inclined by a predetermined angle with respect to the bottom surface portion 7 5 8 a of the container body 7 5 8, Body 7 5

The thickness of the side surface portion 7 5 8 b of 8 becomes substantially constant between these virtual planes 7 5 8 c and gradually increases from the lower virtual plane portion 7 5 8 c toward the bottom surface 7 5 8 f In addition, a cross section along the center line that gradually increases from the upper virtual plane portion 7 5 8 c toward the upper opening portion and extends in the vertical direction through the center of the bottom surface portion 7 5 8 a of the container body 7 5 8 a In Upper inner wall surface 7 5 8 d (on the upper virtual plane portion 7 5 8 c above) on the side surface of the container body 7 5 8 and lower inner wall surface (below the lower virtual plane portion 7 5 8 c) 7 5 8 e extends substantially linearly.

In this modification, the boundary region between the upper inner wall surface 7 5 8 d and the lower inner wall surface 7 5 8 e has a predetermined width, so that the workpiece M entering the boundary region is prevented from aggregating. Can do.

(Second modification)

F IG .14 A and F IG .14 B show an enlarged view of the deformed portion of the second modified example of the stirring and deaerator 6 10 of the second embodiment. In this modification, the container body 8 5 8 is used instead of the container body 6 5 8. Other configurations are substantially the same as those of the above-described second embodiment, and thus description thereof is omitted.

In the container body 8 5 8 of this modification, the virtual plane 8 5 8 c is used as a reference instead of the virtual plane 6 5 8 c of the container body 6 5 8. This virtual plane 8 5 8 c is a lower flat region 8 extending in parallel to the bottom surface 8 5 8 f from a portion closer to the bottom surface 8 5 8 f than the substantially vertical central portion of the side surface of the container body 8 5 8. 5 8 g and the bottom of the container body 8 5 8 b, closer to the upper opening than the substantially vertical center, and the lower flat area 5 8 5 g Connect the upper flat region 8 5 8 h extending parallel to f, the lower flat region 8 5 8 g and the upper flat region 8 5 8 h, and pass through the center of the bottom surface 8 5 8 f of the container body 8 5 8 f An inclined region 8 5 8 i which passes through the substantially central part of the line in the container main body 8 5 8 extending in the vertical direction and is inclined at a predetermined angle with respect to the bottom surface 7 5 8 f of the container main body 7 5 8 It consists of and.

Also in this modified example, the object to be processed in the container 85 58 can flow in the height direction (vertical direction), similarly to the stirring deaerator 6 10 of the second embodiment described above. The workpiece M can be agitated and defoamed with high accuracy by an extremely simple structure.

(Third modification) ·

FI G. 15 shows a third modification of the stirring and deaerator 6 10 of the second embodiment. In this modified example, instead of the flat plate-like rotating body 6 1 4, the upper opening of each container holder 6 1 6 is inclined toward the revolution axis L 1, and the rotation axis L 2 becomes the revolution axis L 1. Each container holder so that it intersects at a predetermined angle, for example 45 degrees. A rotating body 9 14 is provided in which the part to which the da 6 1 6 is attached is bent and inclined with respect to the other part (center part). Other configurations are substantially the same as those of the second embodiment described above, and thus the description thereof is omitted.

Even if the rotation axis L 2 intersects the revolution axis L 1 at a predetermined angle as in this modification, the workpiece M can be stirred and degassed with high accuracy.

(Fourth modification)

F IG .16 A and F IG .16 B show an enlarged view of the deformed portion of the fourth modification of the stirring and deaerator 6 10 of the second embodiment. In this modified example, instead of the container 6 2 8, a container body 6 5 8 excluding the lid 6 60 of the container 6 2 8 and an inner container 6 6 2 are used. Other configurations are substantially the same as those of the second embodiment described above, and thus the description thereof is omitted.

As shown in FIG. 1 6 A, the inner container 6 6 2 has a substantially circular opening at the top, and is composed of a substantially circular bottom surface portion 6 6 2 a and a substantially cylindrical side surface portion 6 6 2 b. . This inner container 6 62 is integrally formed of a flexible material such as silicone rubber or fluoro rubber, and accommodates an object to be processed M as shown in FIG. When it is rotated around the rotation axis L 2 after being mounted in 8, the side surface portion 6 6 2 b can be deformed into a shape along the inner wall surface of the side surface of the container body 6 5 8.

In this modification, the inner container 6 6 2 is replaced with the container body 6 when the workpiece M is stirred and degassed.

5 Since it can be deformed into a shape along the inner wall surface of the side surface, the workpiece M can be accurately stirred and defoamed, and the workpiece M can be easily removed from the inner container 6 6 2. It can be recovered.

(Fifth modification)

F IG. 17 is an enlarged view of the deformed portion of the fifth modified example of the stirring and deaerator 6 10 of the second embodiment. In this modified example, the container 6 28 and the inner container 6 62 of the fourth modified example described above are used. Other configurations are substantially the same as those of the second embodiment described above, and thus the description thereof is omitted.

In this modified example, the inner container 6 62 containing the workpiece M is placed in the container body 6 5 8 and then pressed by the inner cover 6 60 a of the lid body 6 60.

6 2 Side 6 6 2 is deformed into the shape along the inner wall of the side of the container body 6 5 8 It has become so.

Also in this modified example, the inner container 6 62 can be deformed into a shape along the inner wall surface of the side surface of the container body 6 5 8, so that the workpiece M can be accurately stirred and defoamed, The workpiece M can be easily recovered from the inner container 6 62.

As shown in FIG. 17, the lower part of the outer peripheral part of the inner lid 6 60 a is cut out over the entire periphery, and this notched part is the side part 6 of the inner container 6 6 2. It may be engaged with the upper end of 6 2 b. In this way, the side surface portion 6 6 2 b of the inner container 6 6 2 can be reliably deformed.

(Other variations)

In the second embodiment described above, when the container holder 6 1 6 is rotated (revolved) in the substantially horizontal direction around the revolution axis L 1 by the rotation drive mechanism 6 1 2, the container holder is driven by the power transmission mechanism 6 1 8. 6 1 6 rotates about the rotation axis L 2 in a substantially horizontal direction (rotation), but the container holder 6 1 6 may not rotate even if the container holder 6 1 6 revolves. However, the rotational angular velocity of the container holder 6 1 6 may be extremely small (for example, about 1/40) with respect to the angular velocity of the revolution of the container holder 6 1 6, and the container holders 6 1 6 The revolution may be rotated at a desired angular velocity.
